I missed almost a week of birth control starting September 13 I missed 2 light blue pills and my first 3 dark blue pills because I misplaced them . I ended up coming on my period September 17 , 4 days earlier than expected . I guess because I missed those pills having irregular periods , I ended up bleeding again on September 24 for 6 days longer than my usual 4-5 days . I wasn't pregnant because I hadn't had sex in a month . Back to taking my birth control regularly , I ended up having unprotected sex October 4 but he did not ejaculate in me . I'm just a little worried because I've been cramping a little ( my next period isn't until the week of October 20 ) , I missed almost a week of active pills but really I feel like without being on active pills for 2 weeks prior to having unprotected sex it was still a mistake .
